A codificação vetorial (VC) é um tipo de esquema de transmissão de modo próprio que normalmente é considerado em sistemas MIMO. Nos sistemas VC, são criados vários canais de código correspondentes aos autovalores da matriz do canal. No entanto, quaisquer canais de código com valores próprios baixos causarão uma degradação no desempenho. Neste artigo, é proposta modulação e codificação adaptativa (AMC) para um sistema VC. Além do AMC, o número de canais de código é alterado de forma adaptativa pela eliminação do canal de código. Mostramos que o desempenho do BER do VC é melhor que o do MMSE. Em segundo lugar, também mostramos que o desempenho do rendimento do esquema proposto é melhorado em comparação com o rendimento máximo de cada MCS individual.

Abstract: Vector coding (VC) is a kind of eigen mode transmission scheme which is typically considered in MIMO systems. In VC systems, several code channels corresponding to the eigenvalues of the channel matrix are created. However, any code channels with low eigenvalues will cause a degradation in performance. In this paper, adaptive modulation and coding (AMC) for a VC system is proposed. In addition to AMC, the number of code channels is adaptively changed by code channel elimination. We show that the BER performance of VC is better than that of MMSE. Secondly, we also show the throughput performance of the proposed scheme is improved compared with the maximum throughput of each individual MCS.
